Consider the titration of KHP with NaOH. State the reaction that governs this neutrilization. Explain what is the stoichiometry between the acid and the base? If .4728g KHP requires 22.86mL of NaOH to reach the phenolphthalein pink end point what is the molarity of the NaOH? Molar Mass of KHP is 204.22 g/mol.
-Define what is assumed to be equal at the end point that allows you to carry out this calculation?
